Specification of Letters Patent. Farygw@ 559,33*, @91th, Application filed January 8, 1909. Serial No.

To all', whom it may concern:

Be it known'thaty L J oms' BJORKLUND, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and' usefullmprovements'in Non-Refillable Bottles, of which the following is a specification.

The object of my invention is to provide a device of the classv specified which has Jeatures of novelty and advantage. v

Figure l is a vertical sectional view of the D neck of the bottle7 containing the improvev ment, on ythe line of the bottles diameter.-

Fig. 2 is a similar view of the bottle inverted. Fig. 3 is a sectional view of `the bottle on the line L a. V VJ Near the top 'of thenec'k of the bottle at w16 is an annular recess. At the point 9- is an an`nular collar, extending downward from which are series of alternate ridges l0- and the grooves g11-- preferably four of each. These ridges project from the inner surface of the neck of the bottleuand are shown in F ig. 3. They are partly cut away at 1S- forming the shoulders 7 and 8. There are alsocut into these ridges circular recesses -14t. the lower end of the neck of the bottle is situated the valve seat -12-.- lVhen the bottle is in its upright position asV shown in Fig. l, the ball -1- lies in the valve seat 1Qf, eifectually closing theaperture and preventing any liquid from being forced into said bottle below said valve seat. The cup LL- rests upon the ball -1 and helps retain the ball in its place 'in the valve seat.

)After the ball k--1- and the fcup Q- are placed in the positions as shown in Fig. 1, the plate Jlis then inserted in the bottle and pressed down to a horizontal position resting on the shoulders 7-.-. The plate -f4-- may have a plane lower surface or may have a boss -l5- projecting therefrom. Above the plate ilis astopper -5- which is next inserted in the bottle.

. It is composed of two parts of semicircular shape and, when inserted in thebottle, these two parts are placed in the position shown in Fig. l with ytheir shoulders underneath the shoulders -48-. ln the lower end of "the two parts of the said stopper are recesses inldicated by the line -lS--. When the stop- `per is first inserted as stated it is in the position shown in Fig. l with the semi-annular ridges l9- in the recesses -16 and -the two parts of the stopper separated at its upper end. A wedge is then inserted in this opening between the two parts of the stopper and is driven down to the plate rlhe insertion of this wedge farces the'two lower ends of the two parts of the stopper into the recesses 413- and causes the upper end of the parts of the stopper to come firmly together. it. is apparent .that

vthe stopper cannot new be removed without breaking the bottle.

Then the bottle is inverted, as shown in bottle` approaches a horizontal position and force the bottle 1p1 into' the valve seat. It is aided in this respect by the boss --15-, along the' inclined surface of which the rim of the cup moves and it is forced thereby against ball -'l"-, thus making said valve doubly effective.

In most so called nonlretillable bottles when the bottle is in vertical position, by shaking the saine' vertically the valve can be releasdd s o 'as to allow the bottle to be refilled. ln lmy device the valve cannot be moved while in a vertical position as the cup -2- drops into the recesses --ll-d in such a Way as to prevent the valve from being moved by shaking thebottle.

Claims. a

l. vln a' non-rellable bottle, a valve seat, a valve in the neck thereof, cup normally above said valve adapted tehold said valve in its valve seat, and to release said valve when bottle is inverted, a wedge above said cup, a stopper composed of two parts adapt ed to receive said wedge.

2. ln' a non -rciillable bottle7 ridges on the inner surface of the neck thereof, a valve seat. and valve in said neck, a cup normally above said valve adapted to forge said valve into said valve seat, a plate above said cup,

and a stopper; means for permanently bindl seat, recesses in the neck of the bottle which ing said stopper in said neck substantially as described.

3. lira non-rellable bottle, a valve seat and a valve in the neck thereof, longitu`I dinal ridges on the inner surface of said neck, recesses 1n sald ridges, a cup above 'said Valve adapted to enter said recesses, when the. bottle approaches a horizontal fr'om an inverted position, and to force said valve into valve seat, a plate having a boss on its lower surface, a -stopper above said plate adapted to be inserted into and held in position substantially in the manner described.

4.. In a non-reillable bottle, a valve seat, a valve in the neck thereof, a cup adapted to release said valve and to bind it in its valve contain the cup in its binding position and .a stopper at. some distance above said valve.

5. In a non-refillable bottle, a valve scatand a Valve in the neck thereof, a clip adapted to release said valve and to bind it in its valve seat, recesses in the neck ot the bottle 'In testimony whereof I atlix my signature :Y

in presence of two witnesses.
